Answer:
There are 1.8 moles of aluminum.
Explanation:
To solve this problem we need to convert moles of pyrophillite (Al₂Si₄O₁₀(OH)) into moles of aluminum (Al):
- In one mol of Al₂Si₄O₁₀(OH) there are two moles of Al.
With the above information in mind we can now <u>do the conversion</u>:
- 0.900 moles Al₂Si₄O₁₀(OH) *
= 1.8 mol Al
Thus the answer is that there are 1.8 moles of aluminum.
Answer:
Hypsochromic compound, More polar solvent
Explanation:
Hypsochromic shift refers to the shift of solution colour to blue side of the visible spectrum (blueshift) with increasing polarity of the solvent. In our case, the solution changes to orange colour from red when solvent is changed. This means that the emission spectrum of the solution underwent blueshift. (As orange colour is on the 'blue' side for red colour.) So this is a hypsochromic shift, and the new solvent is more polar that the previous one, as it caused hypsochromic shift.
